I ran the impact stats for Mitchell vs Rubio and dated it from Jan 8th (Rubio injury) to now
here, and advanced metrics
here - some points about things that interested me but feel free to check the stats yourselves.
- Mitchell has shot the 3 better with Rubio on the floor vs when he's off, but Mitchell has a slightly higher TS% with Rubio off the floor.
- The Jazz' offense is significantly better with Rubio on the floor vs when he's off. A common misconception during the Mitchell at PG stint is that the offense improved when in reality the offense kinda got worse except for Mitchell's individual offense which obviously was at an all star level during that stretch, but the defense was significantly better during that stretch. I would argue that's more to do with the schedule at that time than any defensive deficiencies that Rubio might have, but the Jazz DRTG with Rubio on/Mitchell off might suggest otherwise.
- To add further to the last point, the Jazz as a team are significantly more efficient with Rubio/Mitchell on the floor vs when Mitchell is on but Rubio is off. All of the other starters + Crowder and O'Neale get more inefficient when you take Rubio off the floor but leave Mitchell on, Favors in particular suffers badly going from a 59.7TS% to a 49.8TS%.
- Mitchell becomes more ball dominant/ball stopping and chucks more with Rubio on the floor going off AST%s vs when he's off, which is something I think Mitchell could do a better job of when playing next to another playmaker. He doesn't need to ball stop just because Rubio is in the lineup to playmaker.
- The Jazz' ORTG with Mitchell on the court and Rubio off is actually worse than the Jazz' ORTG with Rubio on and Mitchell off since January 8th. The Mitchell on/Rubio off Net Rating is higher because the Jazz have been significantly better defensively in those minutes, whereas they've been kinda bad defensively with Rubio on/Mitchell off (another stat that suggests the "offense is better with Mitchell at the point" narrative is a myth).
